How change tomcat8.exe listening port 0.0.0.0:12345 to a different
port
Hi everyone,
In our Apache Tomcat 8.5.31 installation, Tomcat8.exe ist listening on TCP port 12345, and we need to change this to a different port number.
Unfortunatley, we cannot find a way to change this since it is not specified in server.xml or Java options. Does anybody know how this port can be changed?
For full details (server.xml etc.) see: https://serverfault.com/questions/980452/how-change-tomcat8-exe-listening-port-0-0-0-012345-to-a-different-port
Thanks,
Patrick

And just for fun, I searched Google for "tcp port 12345" and found this among others :

Thank you very much for your prompt and detailed feedback.
Unfortunately, there are no such entries in the "web.xml" files within "webapps". Logfiles do not show such entry either.
We therefore have to get in touch with the software vendor in order to address this.
Thanks again.

If you need to go dow to the tomcat applications level :
Under the tomcat top directory, there is a sub-directory "webapps" containing the applications that run under tomcat. Each of those webapps corresponds to a sub -directory of tomcat-dir/webapps/.
Under each of these sub-directories, there should be a sub-directory named "WEB-INF", which contains a file "web.xml" specific to this application. If the application opens any TCP port by itself, chances are that it is mentioned as a parameter in that web.xml file.
Another good source may be the tomcat logfiles, at the moment tomcat starts.
The logfile usually contains messages indicating when tomcat opens ports and/or starts applications, and the applications themselves may also write there when they open a port.
(That depends of course on the application, and how helpful its logging is).
Good luck.

Short version : run tomcat8w.exe, and examine the various tabs to see if you find your
port 12345 somewhere there (maybe the JVM is listening for JMX or so). Otherwise, it must
be (also) an application which tomcat is running, which opens its own port 12345).
Long version : read
https://cwiki.apache.org/confluence/display/TOMCAT/Windows#Windows-Q11
to find out what tomcat8.exe and tomcat8w.exe really are.
short version of the long version :
server.xml shows the ports on which /tomcat itself/ is listening.
But tomcat8.exe is not "tomcat". It is a wrapper program, which runs the JVM which runs
tomcat, which runs applications. The JVM itself, and the applications, may open ports,
without tomcat even knowing about them.
Let us know if that helps.
